The FSReborn modeling of the Sting S4 features:

Realistic night lighting, exterior lighting, and ambient lighting inside the cabin.
CFD (Computation Fluid Dynamics) and new MSFS prop physics fully implemented into the flight model.
Realistic flight model tested by Sting S4 pilots.
MSFS rain and icing effects included.
Highly accurate 3D model and animations.
Opening canopy.
Full custom engine carburettor physics modelled, this includes choke behaviour due to ambient + engine temperature, inverted flight consequences and many other real world behaviours.
Full custom coded checklist as per original aircraft POH (Pilot Operational Handbook) with interactive co-pilot.
Tablet EFB to operate many options of the aircraft, including fuel, weight, chocks, pitot tube cover, tyre pressure, break pads, battery charge, engine maintenance, lighting bulbs and many more.
Custom maintenance module (via the EFB) which manages wear and tear to many components of the aircraft alongside with realistic behaviours, failures and consequences in your flight such as, engine failures, brake failures, electrical failures, tyre's air pressure and many others real world circunstances encountered by real pilots.
BRS (Ballistic Rescue System also known as CAPS) full implemented and operational, designed with custom physics and flight model. This is the first aircraft in MSFS capable of bringing this technology and experience to users.
Full GTN750 integration (PMS50).
4K highly detailed PBR textures for the best immersion experience possible.
11 liveries included.

The TL-2000 Sting S4 is a two-seat, single-engine, low-wing light sport aircraft from TL Ultralight of the Czech Republic. The airplane, introduced in 2010, is constructed of 85% carbon fiber composite and is a renowned performer. Its design is based on its predecessor, the popular TL-2000 S3, itself a version of the company’s TL StingSport.

The TL-2000 Sting S4 features a main wing with a span of 29 feet, 11 inches, fixed tricycle landing gear, side-by-side seating, and a traditional tail unit. The aircraft can be fitted with any of three Rotax engines: the 912 ULS, the 912iS, or the 914. The S4 cruises between 112 and 155 miles per hour, climbs at 1,000 feet per minute, and has a range of 520 miles.

The TL Ultralight TL-2000 Sting S4 is a craft that looks just as it functions: sporty. A performer at a range of speeds, it is also forgiving, allowing aviators to cruise leisurely on sightseeing flights, or push their piloting skills to new heights.
